ily imorovement relates to machines for cleaning carpets, and the like, andhas for one of its objects 'the provision of simple and efficient means for quickly and p efficiently A cleaning carpets, rugs, and the like. A further object is the provision of a machine of this character adapted to rinse out dust from a carpet, or the like, before the actual scrubbing and cleaning has been begun.

A further object is the provision of a machine of this character having elongated brushes which operate reciprocally across a carpet, or the like, to be cleaned.

A further object is the prov'sion of etlicien't means for holding a. carpet while being acted upon by brushes.

A further object is the provision of means for we ting a carpet and preliininarily scrub-y bing the carpet under water before the actual cleansing has been begun.

A still further object is the provisioirof means for scrubbing a carpet in one direction across the nap in clear water preliininarily before scrubbing the carpet in a different dim rection across the nap during the'application of soap or other cleansing means with water.

Other objects will appear hereinafter.

An embodiment of my invention is illustrated in the accompanying drawings forming a part of this specification and in which- Y 1 is a side elevation of the part of my machine for preliminarily wetor 'the like, and freeing dust Fig. improved ting a carpet, therefrom Fig. 2 is a same;

Fie'. 3 is a section taken on line 8-3 of and Fig. 4l is a. view of the feeding end of said device;

5 is a plan view of the scrubbing and cleaning part of my improved device; t

Fig. 6 is a side elevation of the device shown in Fig. 5; h n

TEig. 7 is a longitudinal section of the same; and l i 8 is a fragmental section taken on line 8-5-3 of Fig. 't'.

l lind that by immersinff a carpet, or the Elke., in water andprelir rily agitating the surface of said carpet the loose dust will fragmental plan View of the ybetaken from the carpet and that such carpet will be more easily cleaned by the regular cleaning mechanism kthan where it is attempted to free the carpet of the loose dust' by beating or by dry suction. A device adapted to accomplish the aboveresult is shown in the accompanying drawings,.in

which'a frame 10 of somewhat rectangular construction is indicated. It will be apparent that the frame may be formed of any desired material and of a size and shape to support the parts to be carried thereby. In the present construction I have formed the frame 10 so as to have angular guides 11 at its corners. 2. rthese guides 11 provide the corner posts of tie frame 10. Between said guides 11 I mount a tank 12 which is of a size to extend under the working parts mounted on the frame 10. rl`he tank is adapted tobe moved vertically so that when it is desired to clean or inspect such tank, the latter can be low-k ered to the bottom of frame 1() for easy cleaning or inspecting. As a means for mounting tank l provide bands 13 at its ends which extend up to the top of the tank and at the top of said bands are connected the endsof cables 14, one cable 1li at each side of the machine. The cables 14 each pass over two pulleys 15 mounted in the frame 10 and are wound around a drum 16 intermediate the cnds of the frame. The two drums, one of which is shown, are mounted on a shaftv 17 which extends across the frame 10. One end of shaft 17 is provided with a crank 18 for manually rotating the drums 16 to raise and lower the tank 12. Villen the tank has been raised to its operative or upper position dogs 19 are moved under the tank so as to take the strain ofi of cables 141. These dogs 19 may be mounted and operated in any desirable manner. l have indicated them as being lined on a shaft 2O at each side of frame 10. Each of the shafts 2O had a lever 21 fixed thereon and the levers 21 connected together by a link 22 so that by operating one of-said lshafts 2O both of the shafts with theirdogs 19 can be moved under the .tank 12 forsupporting the latter or moved out from under the tank when it is desired to lower the latter.

two of said guides being shown in Fig. y

The tank l2 may be provided with a partition 23 so as to provide a compartment 24 lfor the reception of a roll of carpet to be cleaned. It will be apparent, however, that the carpet may be held in any desirable manner, but the compartment 24 provides a convenient place for holding such carpet in a roll in position for easily feeding into the dusting machine. Y An edge of the carpet is Vtaken up over the top of partition 23V and invthe delivery end of the endless table 27 so as to conduct the carpet away from said table 27. The latter may be provided with a supporting member 3l under its upper run, as indicated in Fig. 3, to hold its upper surface in substantially a horizontal plane.

At the end of stripper plate 3() are two rollers 32 and 33. The roller 32 is fixed on a shaft x 34 mounted in bearings in the frame l0. The

-roller is fixedy on a shaft mounted in bearings adapted for'movement away from roller 32. Any suitable form of mounting the bearings of shaft 35 may be provided an'dthat indicated is a convenient form in general use in machines of this character.

A roller 36 is positioned adjacent roller 33 and fixed on a shaft 37 mounted in the frame 10 similarly to shaft 34. The arrangement of roller 33 and its mounting is such that the roller 33 moves away from rollers 32 and 36 atl the same time. Around the rollers 32 and 36 are a number of endless cords 38, or the like, which serve to hold the carpet against roller 33 and guide such carpet between rollers 32 and 36.

Above roller 36 is a roller 39 fixed on a 'shaft 40 which-is journaled in the frame 10 similarly to shaft 35 so that the roller 39 can yield away and toward roller 36. The cords r38 may also pass around a small roller 4l suitably mounted in frame l0 so as to hold the carpet up 'against roller .39 and raise the carpet up over the edge yof'tank 12.

A water supply pipe 42 is arranged so as to discharge water into tank l2 and preferi which the carpet is passed.

ably between certainv of the rollers between I have found that said pipe 42 works advantageously by being positioned between rollers 39 and 33, as indicated inFig. 3. The tank l2 is also provided with an overflow pipe 43 which may be of flexible material so as Vto permit the vertical movement of tank 12, as already described. The overflow pipe 43 isy preferably at aY height'v so that the water will be maintainedy in tank l2 above the top of table 27 'so as to immerse a carpet while being passed over said table. As soon as the carpet leaves `operated inany approved manner.

with the clean water issuing from pipe 42V where it is rinsed, and then such carpet is passed between rollers 36 and 39 for wringing the same. YThe rollers 4l and 39 further tend to wring the carpet again.

y While the carpet is on table 27 I preferably agitate the upper or nap side of such carpet so als to free dust and larger particles of foreign material Vin said carpet. A set of brushes moved back and forth on the carpetunder the water serves as an efficient means vfor dislodging suchl dust and other particles. I have indicated four brushes 44 which are considerably longer than their width and'mounted acrossV the frame transversely of the `path of the carpet through thel machine. These brushes may be mounted and I have indicated guides 45 extending through the portions of the frame lOwhich support the Vthe stripper 30 rollers 32 and 33 squeeze out carpet guide rollers, the bars being supported by these portions of the frame. Upon the guides 45 area plurality of members 46 which are secured to the tops of the brushes 44 in any approved manner, such as by they screws indicated. As a reinforcement for the brushes I have indicated a longitudinally eX- tending bar 47 above each of said brushes audits corresponding guide. These bars47 are secured to the members 46 as clearly indicated. 'Io each of the bars 47 is secured an upstanding ear 43 and each of the ears 43 is connected by means of a link 49 to a crank shaft 50. The crank shaft, of course, has a separate crank for each of the links 49. The crank shaft 50 is mounted in suit able bearings land connected by means of sprocket gearing 5l to a shaft 52 which in turn is connected by suitable gearing in a housing 53 with a motor54. The shaft 52 may also be connected through suitable gearing in housing 55 with the shafts 34, 35, 37 and 40 so as to operate the rollers on said shafts. It will be apparent that the surface speeds of rollers 32, 33, 36 and 39 are sub stantially the same as the surface speed of table 27.

On rollers. 33 vand 39 I preferably provide wrappings of rope 56 so that while the carpet is squeezed in passing through the rollers as aforementioned, there Vare still pockets in the rollers 33 and v39 permitting a quantity of water to run along on the top of the carpet.

vThe foregoing parts are those for rinsing out loose dust and other particles of foreign material from the carpet before the actual cleaning and scrubbing has been begun.

Heretofore the dusting has been done by beating an-d by suction means, and oneof the liniinarily remove dust from carpets by rinsing such carpet before actually scrubbing the saine. j

I have indicated a frame 60 of suitable size and shape to support lthe Vscrubbing apparatus. The form shown simply indicates a means for holding these parts and may bel varied as desired. 1n Figsl to L1, 'inclusive7 this part of the mechanism is considered as being viewed from one side, and in Figs. 5', 6, 7 and 8 the rest of the machine is being viewed as from the opposite side of the machine.

After the carpet leaves the mcchanismin frame and passes from roller i1 it is passed side of the carpet and that under the roller engage the other side of the carpet. 1n this manner the soap is applied to both sides ef the carpet and readily adheres to the carpet since the latter is wet from the apparatus in frame 10. The roller 63 may be mounted in any desirable manner, such as being fixed on a shaft 64 mounted in frame 60.

In the frame is mounted a tank 65 which has one end adjacent trough 61 and is adapted to contain water and the other scrubbing agents used in cleaning a carpet. The tank 65 may have any desired form and may be mounted as indicated in Fig. 7 so that it cannot be moved in frame 60, or, itrnay be mounted similarly to tank 12 in frame 10, as al-A ready described. Said tank 65 preferably has the end adjacent trough 61 lower than the other end so as to insure that the water and liquid soap or other cleaning agents will drain back toward said trough 61.

1n tank 65 adjacent trough 61 is a brush 66 fixed on a shaft 67 mounted insuitable bearings in frame 60. Above the brush 66 is a roller 68 having short bristles 69 thereon and spaced points 70. The bristles provide a firm backing for holding the carpet against 'brush 66 during scrubbing of the bottom of the carpet. The points 7 O engage the top of the carpet and both feed the carpetvalong and prevent such carpet from being moved too fast by brush 66. The carpet after leaving brush 66 and roller 68 is directed onto an endless table 71 which is mounted on rollers or sprockets 72 fixed on shafts 7 3 and the latter mounted in suitable bearings in frame 60. The upper run of the. table 71 may be provided with a support 741 for holding the top surface of such table in a substantially iori- Zontal plane.

The table 71 preferably has a' plurality of points 7 5in its outer surfaceso as to engage thercarpet passing over such tablefand holding the latter against movement onthe table bv the cleaning elements to be describedl later. A resilient member 75 be provided so as to press the carpet down onto point 7 5, as clearly indicated in Fig. 7 Above the table 71 1 provide a plurality cf elongated brushes 76. In the form shown there are two sets of the brushes 76- 'and suoli brushes disposed longitudinally of the path of the carpet through the machine. 1t will `be apparent that a fewer Or greater numberv of sets. of these brushes may be provided. f

VThe brushes 76 may be mounted for reciprocatory movements in any desirable manner.v 1 have indicated each of the brushes 76 having a link 77 adjacent each end and piv-V oted to downwardly extending ears 78 ona head 79. Also pivoted to the tops of the ends of brushes 76 arerods 80 which extend upwardly through the heads 7 9, as clearly indicated in Fig. 7. Between the heads 79 and the pivotal connections of the rods 80fwith the brushes 76 are compression springs-'81 which tend to press downwardlyron the brushes forcing the latter toward the table 71. Each of the rods 80 is provided with a nut 82 threaded thereon vfor limiti-ng'the., movement of said brushes toward the table 1. 1n use the nuts are preferably arranged so that the brushes cannot quite touch the table 71 but-can engage the carpet and apply sufiicient force thereto to effect eflicient scrubbing of the carpet.

v'lhe heads in eash set of brushes 76 are as clearlyindicated in Fig. 6. The upper,

ends of levers 85 are connected by links 87 to the mountings of Vtwo of the hars 88. 1 rEhe lower portions of said levers 85 are connected by means of llinks 88 to the other two bars c.) so that alternate bars 88 move in one direction, while the other twofalternate bars 88 are moved in vthe other direction. This.

causes alternate brushes in each set to .move f in one direction, while the other alternate brushes in such set move in the other direction. The lower ends of levers 85 are connected by means of links 88 with crank pins 89v on shaft 67. -lt will `be api-parent that the brushes 76 and 66should be moved at greater speeds than the speed-ofthe carpet through the machine while rcllers 63, 68, and table 71 are inovedvat substantially the speed ofthe S'aid bars 83 arel mounted on guidesk CTL i :or

carpet through the machine. Any suit-able vided. The shaft 67 is indicated being` connected to shaft 73 by a'sproclret and chain gearing with a difference of speed indicated and it will be apparent that shaft 67 should be Y '10 rotated as muchy faster than shaft- 73 as necessary to accomplish-,the desired speeds of brushes 66 and'76 lto] eectively scrub the carpet. f

Between the brushes 76 I providevthin plates which are adapted to hold the carpet down on table 71 and facilitate holding thecarpet against-the action of brushes vThese Aplates 90 may be mounted in any de-V irable'manner, vsuch as by providing upstanding rods 91 which pass through bars 92 extending across the frame. Around each rod 91Vis a. spring 93 whicn tends to force its yplate downwardly toward the table 71. A nut 94' is provided on each ofthe rods 91 to limit the downward'movement'of the plates 90 'so' that the latter exert sufficient p on the carpet and be held away from table 71 Y when there is no carpet in the machine.

At Aan end of tanlr65 is provided a rinsin tank 95V and a pair of wringingrollers 93 provided; to wring the carpet as it passes from the machine. Before the carpet wrung by rollers 96 water supply pipes 97 are adapted to discharge water against the upper and lower sides of the carpet kas clearly indicated in Fig. 7. As soon as kthe water rinses off the soapy water used in the scrubbing, the carpet is wrung by rollers 96 and is then ready to be dried. The rollers 96 are indicated as fixed onv shafts 98 which are mounted in suitable bearingsin frame 60. The shafts 98 are connected together by gears 99 and one of said gears 98 is connected by a belt or other gear` ing 10() with one of shafts 73, see Fig. 6,

lI preferably provide thinywires 101 which ext-'end across the tops of tank 65 so 'as to conduct carpets through the machine and strip such carpets off of table 71 and insure the passage of such carpets through the machine. One end of each of the wires is connected as at 102 1n the machine, andA the other end secured as at 103.

In Fig. 5 it will `be apparent that the brushes 76 at one side of the levers 85 are cifset or staggered with relation to the brushes at the other side of said levers so that :one set of brushes will scrub any spaces left between the brushes of the other set. Also, the Vplates 90 are staeeered lso as'to bedisposed between the brushes as just described.
